+\begin_layout Standard
+The interpreter and task are carefully written so that the only limit on
+ part program size is disk capacity.
+ The TkEMC and Axis interface both load the program text to display it to
+ the user, though, so RAM becomes a limiting factor.
+ In Axis, because the preview plot is drawn by default, the redraw time
+ also becomes a practical limit on program size.
+ The preview can be turned off in Axis to speed up loading large part programs.
+ In Axis sections of the preview can be turned off using special comments.
